aluminum sheet 5052 API standard 650 mechanically-anchored tanks
The internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API standard 650 mechanically-anchored tanks External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.
Inspection of weld and micro crack of API standard 650 mechanically-anchored tanks: the inner and outer surface of API standard 650 mechanically-anchored tanks, weld and heat affected zone shall be observed by naked eyes first. 100% ultrasonic testing or 100% penetrant testing are carried out for butt welds of API standard 650 mechanically-anchored tanks. For the defects found by 100% magnetic particle inspection, dye detection, 100% ultrasonic inspection or 100% penetrant inspection, the radiographic inspection shall be used again to ensure the accuracy of the test results.
Inspection of Welded storage tanks Surfaces Exposed during FabricationThe edges of API standard 650 mechanically-anchored tanks plates, openings and fittings exposed during fabrication shall be inspected carefully to make sure that any defects have been uncovered, as well as to determine that the work has been performed properly.Minor defects found may be repaired only after the inspector approves the method and extent of repairs. Materials that have more than minor defects that cannot be satisfactorily repaired shall be rejected.Spot radiographic or ultrasonic examination shall be not less than 6 in. extending along the weld. Spot radiography shall comply with the standards given in 7.15.1.3. Where spot radiographic or ultrasonic examination is applied at joint intersections, the surface shall be prepared and examined for a distance of 3 in. on each side of the intersection, making the minimum length of examination 6 in. on the horizontal weld and 3 in. on the vertical weld.
Our quality control department will do inspection for details of the steel materials API standard 650 mechanically-anchored tanks before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
